Control (2007)

The Issues: Ian's career as an indie icon drives a wedge between them, especially when he starts an affair with journalist Annik Honore (Alexandra Maria Lara). The fact he's suicidally depressed doesn't help.

How To Fix The Relationship: Tragically, all this one needed was a few years. By the late 1980s, they'd all have been doing Es at the Hacienda and everything would have been wicked.

Kramer vs Kramer (1979)

The Couple: Ted and Joanna Kramer (Dustin Hoffman and Meryl Streep).

The Issues: Technically, these two are no longer a couple, but it's depressing enough watching them fight for custody of their son Billy (Justin Henry).

How To Fix The Relationship: Has neither of them heard of shared custody?
